I am going to work for a new school in February, and the school is new to this visa stuff. They asked me today, "What kind of passport do you have?"

They already know I "am/was" on a Z visa before entering China, but they were asking about my passport. They also already know I am from the US.

Has anything recently come up, specifically in Beijing that I might need to be aware of regarding changing schools?

From my understanding, since last year in May we needed a Foreign Expert Certificate. However, after that is processed, all we need to do is show up at the PSB near Yonghegong in Beijing and they put a residence permit sticker in the passport. Then it's done.
